CT guided percutaneous radiofrequency thermal ablation of peripheral lung carcinoma / 中华放射学杂志

ABSTRACT

Objective To assess the therapeutic value of CT guided percutaneous radiofrequency thermal ablation(RFA)for peripheral lung carcinoma(PLC).Methods Forty-three patients with PLC were treated with RFA under the CT guidance.The patients included 26 males and 17 females,and the age ranged from 52 to 76 years.The CT guided percutaneous biopsies were performed to obtain the pathology before the procedures.Results The operations in all cases were successful,little amount of pneumothorax was found in 3 cases,liquid-pneumothorax in 1 case,and large amount of pneumothorax was drainaged in 1 case.The volume of the lesion in 40 cases from 43 patients was diminished gradually at 3 and 6 months follow-up after the procedures.No change in the volume of lesion with peripheral enhancement was seen in 3 cases.Conclusion CT guided percutaneous RFA for PLC is a safe,effective,and minimal invasive procedure.
